We’re always looking for new and better ways to respect our grape sources so that we can make the most precise, age-worthy wines with upfront opulence and the structure to evolve.”

Our Journey

Founders Dan Kosta and Michael Browne started out with humble beginnings while working together in a local restaurant in 1997. Full of passion but short on capital, Michael developed relationships with key growers in Northern California, while Dan, along with the help of a third partner, Chris Costello, worked to market and sell the wines.

In 2011 we were named Wine Spectator’s #1 Wine of the Year with our 2009 Sonoma Coast Pinot Noir. It was an honor that could only fuel our steadfast dedication and focus on quality. We have remained committed to embracing innovation, pushing boundaries and we welcome unconventional approaches in the cellar to make irresistible Pinot Noir and Chardonnay wines of elegant intensity.

These varieties reflect their growing conditions and winemaking approaches like no other and we are obsessed with capturing the individual expression of the state’s finest growing regions—the rugged and diverse Sonoma Coast, the foggy Russian River Valley, the chilly Santa Lucia Highlands, the coastal proximity of the Sta. Rita Hills and the wild, untamed Anderson Valley.

Through the artful blending of our vineyards and their individual blocks and rows, we strive to create the purest expression of each appellation’s unique personality.

Beyond our craft, we relish in extending our commitment to excellence through our signature approach to hospitality. With every bottle, we aim to tell the story of California’s most sought-after wines and invite you to join our KB community on this journey.

Every vintage, we work tirelessly to tell the story of these chosen regions and vineyards through the medium of wine.
